风管组装:风管较短可以一次性在地面组装,风管较长可依据安装场地情况分段组装。组装时应尽量调整风道的中心度和水平度,避免风管扭曲或上下起波,左右摆龙,每段风道不宜超过10m。组装时,垫片应垫平,法兰螺栓应均匀拧紧,螺母帽均朝向同一方向

极速时时彩官网Air duct assembly: the wind pipe is short, can be assembled on the ground at one time, the wind pipe is long, can be assembled according to the installation site. When assembling, the center and levelness of the air duct should be adjusted as much as possible so as to avoid the distortion or upward and downward wave of the wind pipe and the left and right swing, and each section of the air duct should not exceed 10m. When assembled, the gasket pad, the flange bolts should be tightened evenly, nuts are toward the same direction

极速时时彩官网风管就位:先检查全部支架的水乎度、标高、牢固程度。风管就位一般使用直接和吊具两种方式。如果风管断面较小位置又很低的可采用人工就位方法,只需搭设简易脚手架即可。当风管断面较大且管段较长时,可采用滑轮、倒链、大绳等方法吊装。

Air pipe in place: first check the water level, elevation, firmness of all the supports. Two ways of direct and hanger are used in the air pipe. If the cross section of the duct is small and the location is very low, the manual placement method can be used, and only a simple scaffold can be built. When the cross section of the air duct is large and the pipe section is longer, the pulley, the chain and the big rope can be used for hoisting.

极速时时彩官网为了便于风道就位,一般多采用将风道吊在脚手架上,然后再将其抬放在风道支架上的方法。脚手架应沿其风道长度方向搭设,高度和位置应适合施工操作,吊装顺序应先干管后支、立管。

In order to make the air duct in place, it is generally used to hang the air duct on the scaffold, and then put it on the support of the air duct. The scaffold shall be erected along the length of the air duct, and the height and position shall be suitable for the construction operation. The lifting sequence shall be dried, supported and supported.

风道调直:就位在支架上的风道,应拨正位置,调整风道横平竖直,然后再按图集要求固定。

Duct straightening: in place on the support of the air duct, should adjust position, adjust the air duct vertically, then according to the requirements of atlas fixation.

就现阶段来看,我国国内建筑通风管道类型多使用镀锌钢板风管,但是,种种案例与科研数据显示,钢板风管的耐火性能并不理想,为了改善防火性能,可以将防火材料包覆在钢板风管表面,通过这一方式可以达到1~2h防火性能,这样即可满足防排烟管道设计需求。

At this stage, China's domestic construction ventilation pipe type multi use galvanized steel duct, however, all cases and research data show that the fire-resistant performance of wind pipe plate is not ideal, in order to improve the fire performance, fire prevention materials can be coated in the surface of steel duct, through this way can reach 1 ~ 2H fire the performance, so you can meet the design requirements of smoke exhaust pipe.

极速时时彩官网根据我国《建筑防排烟系统技术要求》的相关规定,为了保障排放管的防火效果,排烟管在穿越防火区域以及排烟管道吊顶时,需要控制好管道耐火极限,一般情况下,耐火极限必须要保持在1h以上;同时,排烟管道应该禁止穿越楼梯间与建筑物的前室,如果穿越出现困难,就需要调整耐火极限,将极限控制在2h以上。

According to the relevant provisions of China's "building protection requirements" exhaust system technology, in order to ensure the effect of fire discharge pipe, the exhaust pipe in the exhaust pipe through fire area and ceiling, the need to control the pipeline fire resistance, under normal circumstances, the fireproof limit must be maintained at more than 1h; at the same time, the exhaust pipe should be banned across the front stairs between the buildings, if through the difficulties, we need to adjust the fire resistance limit, the limit control over 2h。
